forces of inertia which will. counterbalance the unbalancedforces at any'instant balancing of the masses will be; complete. There is, however, a further condition necessary for steady running. The centrifugal forces which act upon'thc sprung part and those which act upon the non-sprung part must each be in equilibrium in order to prevent stressing the fixation, of th If (a is the M and M and r the radius of the crank (Fig. 1) then each element (2, m of a coupling rod will be acted upon by the cen- This force/may be e system.

The point C (Fig. 2) the unction ofthe four coupling rods AC, BC, DC and EC is therefore acted'upon by four forces of this kind resultin from the corresponding parts of the centrifugal forces of thefour rods.

Their resultant R is equal to the sum of the four forces.v Their action is trans I mitted to the crank'pins A and -B, by the.

rods AC, BC; The crank pins A and B are ---r0ds AC and BC,
